Knights announce lineups for Round 23

The Newcastle Knights will travel to New Zealand to take on the Warriors for this Sunday's round 23 clash.

Knights Coach Rick Stone spoke about the retirement of Steve Simpson and the Knights game against the Warriors.

"Obviously after the last couple of games we have performed well, there is a bit of buzz in the place and obviously the Warriors have been playing particularly well themselves, so it should be a good contest," Coach Stone said.

After sustaining some rib cartilege damage during the Knights exciting win over the Canterbury Bulldogs on Sunday afternoon, Jarrod Mullen has been given until Thursday to show coaching staff if he will travel.

"Mullo is a big one for us, he has some rib cartilege damage and is still a bit uncomfortable at this stage.

"We will check him again on Thursday and see how he can get through a session."

With a greatly improved home record of four wins from the last four games at EnergyAustralia Stadium, the Knights are looking to take their confidence across Tasman Sea.

"We are looking forward to the challenge and I think the boys have definitely gained some confidence out of the last two games.

"If we are going to make the eight then we need to knock a couple of teams out, and they are probably around that mark."
